Member Function Documentation

YCPValue YECompare::evaluate ( bool  cse = false )

virtual

Execute YCP code to get the resulting YCPValue. Every inherited class of YCode should reimplement this method.

Returns:

YCPValue after executing the code

Parameters:

cse	should the evaluation be done for parse time evaluation (i.e. constant subexpression elimination)

Reimplemented from YCode.

virtual ykind YECompare::kind ( ) const

inlinevirtual

Kind of this YCode. This method must be reimplemented in the inherited classes.

Returns:

the YCode kind

Implements YCode.

References YCode::yeCompare.

YECompare::REP_BODY ( YECompare  )

private

std::ostream & YECompare::toStream ( std::ostream &  str ) const

virtual

Write YCP code to a byte stream (bytecode implementation). Every class inheriting from YCode must reimplement this method.

Parameters:

str	byte stream to store into

Returns:

byte stream for chaining writing bytecode (str)

Implements YCode.

References m_left, m_op, and m_right.

string YECompare::toString ( void  ) const

virtual

Return ASCII represtation of this YCP code.

Returns:

ASCII string representation

Reimplemented from YCode.

References compare_op_string(), m_left, m_op, and m_right.

std::ostream & YECompare::toXml ( std::ostream &  str, int  indent  ) const

virtual

Write YCP code as XML representation. Every class inheriting from YCode must reimplement this method.

Parameters:

str	string stream to store into
indend	indentation level for pretty print

Returns:

string stream for chaining writing XML (str)

Implements YCode.

References compare_op_string(), m_left, m_op, m_right, and Xmlcode::xmlify().

constTypePtr YECompare::type ( ) const

inlinevirtual

Return type of this YCP code (interesting mostly for function calls).

Returns:

type of the value to be returned after calling evaluate

Reimplemented from YCode.

References Type::Boolean.
